That is true. phoenix::value is not default constructible. While it is easy to make it so, I'm not sure it is a good idea as it will potentially break existing code which holds values that are not default constructible. I'd argue that phoenix3 should follow.
OTOH, I think a good compromise is to allow default construction on primitive types and POD structs. That will solve your problem. I can do that now with phoenix-2.
That makes my life easier :) May I ask you to do that? Thanks, Joel. Regards, Michel
